7 days* stubbornly callused and hardened skin remover for feet (and other hard skin areas). SVR XERIAL 50 Extreme Feet Cream is primarily a foot treatment for eliminating corns and calluses in just 7 days. A result similar to using a pumice is achieved but without the need to file brutally away at the skin and, remarkably, with the unique advantage of not triggering a vicious circle 'rebound' effect whereby new hard skin grows even more stubbornly in the place of the callused skin that has just been removed. Also works on similar areas where thickened skin can appear, eg. hands and elbows. XERIAL is a urea-based skincare range for dry, rough, peeling or flaking skin, tackling all levels of dryness. XERIAL products' concentration of Urea varies between 5% and 50% providing different types of skincare action accordingly. Dry, rough skin regains softness, calluses, corns, deep cracks and areas of hard skin are eliminated. No parabens, no fragrance.
